Delivery & Shipping

Shipping costs are calculated based on delivery location.

The Astra is delivered by flatbed trailer. The shipment includes pre-assembled panels and detailed installation instructions. Assembly typically requires two people, basic tools, and a few hours, depending on site conditions and installer experience.

Customers are generally notified approximately two weeks before the scheduled delivery to allow time for preparation. Residential deliveries include freight-company offloading with threshold delivery at no additional cost, according to the supplier's stated delivery terms. Commercial deliveries require a customer-provided forklift or loading dock for unloading.

Please ensure you are prepared to receive and unload the shipment in accordance with the supplier's delivery instructions. Confirm the exact delivery point and unloading arrangements before placing your order.

The sauna is designed to sit directly on existing flooring. The surface must be level and water-resistant; suitable examples include concrete, ceramic tile, vinyl, and laminate. If your flooring does not meet these requirements, an alternative foundation may be needed.
